Nexus - Ultra Si Prostate Massager

The Nexus Ultra Si is both a prostate and perineum stimulator. Thanks to the ridges on the shaft, you feel every detail of the Ultra Si during insertion, and that's exactly the intention. It's a unique stimulator with a stainless steel ball that stimulates the perineum. This ball is easy to remove for cleaning, but you could also attach eStim accessories in this spot. The Ultra Si is easy to use and easy to clean with lukewarm water and a toy cleaner.

Warning when using with the eStim:


Do not use if you have heart problems/pacemaker or heart rhythm disorders.
Do not apply to eyelids.
Do not apply to damaged skin.
Avoid abrupt changes in the shock absorber setting.
Keep out of reach of children.


Only turn on the control unit after you have attached the accessories to the body, not before.
